YARN-SWIFT.

SPECIFICATION forming part of Letters Patent No. 584,264, dated June 8, 1897'.

Application led March 2l, 1896.

To all whom if; may concer-n:

Be it known that I, JOHN B. ELDER, a citizen of the United States, residing at VVinooski, in the county of Chittenden and State of Vermont, have invented certain new and useful Improvements in Yarn-Swifts; and I do here by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains io make and use the same.

My invention relates to improvements in yarn-swifts; and it consists in the particular construction of the several parts hereinafter fully described, and especially pointed out in the claims.

The object of my invention is to provide a swift with radiallyadjustable spring-actuated arms for the purpose of holding the yarn taut without unnecessary care or labor on the part of the operator, and to provide a friction-stop to prevent the resistance of the reel beyond one revolution should the yarn become broken during the windin g operation.

In the accompanying drawings, Figure I is a perspective view of a swift embodying my invention. Fig. 2 is a longitudinal sectional view of one of the radial arms. Fig. 3 is a section taken horizontally below the radial arms of the swift, showing the friction stop or brake.

A indicates a support or bracket adapted to be secured at one end to any suitable object, and O the head or hub of the swift,which head or hub is provided with the radial hollow arms Gr. The hub is journaled upon a spindle or screw B, passing through the same and screwing into the end of the bracket or support A and upon which the swift freely rotates.

Rods I extend into the hollow radial arms G and are held in any desired longitudinal adjustment therein by means of the clampingescrews H. The outer portions of these rods I are reduced, as shown at J, having a collar or washer d at the inner end, and surrounding this reduced portion are the springs K, situated between the washer d and the spring-actuated sleeves L, which carry at their outer ends the yarn-receivers M. These sleeves L are provided at opposite sides with longitudinal openings or slots b, into which the ends of the pins e extend, the said pins passingtransversely through the ends of the reduced portions J of the rods I. By this construction the yarn receivers are held spring-actuated and under tension as the yarn is being wound around them, as will be readily understood, through the medium of the springs K, while at the same time they are bodilyadjustable in or out through the medium of the clamping-screws I-I, which hold them within the hollow radial arms.

A friction brake or stop N is provided, which consists of a strip of sheet metal passing around a collar D, extending downward from the head or hub O of the reel, and having its ends clamped with more or less tension by means of the thumb-screw P. One end of this strip extends outward, as shown at Q, and is adapted to engage a stop R upon the bracket or support A. The function of this brake or stop is to permit the reel to re volve under the desired tension or resistance for winding the yarn thereon, but should the yarn become broken it will prevent the reel or swift from rebounding beyond one revolution by the stop R and thus unwinding the yarn. The amount of rigidity of this stop or brake and also its tension are regulated, as will be readily understood, through the medium of the thumb-screw P, to suit the circumstances under which the swift is being operated.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A swift comprising radially-extending` hollow arms, a rod longitudinally movable within said arms, a sleeve longitudinally movable upon the end of the rod, a stop for the sleeve limiting its movement, a spring upon the said rod having its outer end engaging the inner end of the sleeve, and a stop upon the rod engaging the inner end of the spring, substantially as shown and described.

2. A swift comprising a bracket having one end adapted to be attached to a support, the opposite end extending in approximately a straight line, a hub journaled upon the said bracket transverse J[he straight end, the hub having arms at its outer end, the stop secured to the inner end of the hub and eX- iending in a plane parallel with the plane of the straight portion of the bracket, and

3. A swift comprising a hub, having ra- In testimony whereof I do afx my signadially-extendng arms, a rod longitudinally ture in presence of two Witnesses. adjustable upon said arms, a clamp carried JOHN B.
